Comparing the Casio EX-Z270 and EX-ZR800: Two Compact Persuasions for Distinct Photography Needs

In the world of compact cameras, Casio has often carved a niche with its trimmed-down superzooms and pocket-friendly ultracompacts. Today, I’m diving deep into the Casio EX-Z270 and the EX-ZR800, two cameras that might initially seem similar but, under the hood, cater to mid-level enthusiasts with different priorities and workflows.

Both hail from Casio’s Exilim lineup but come from slightly different eras - 2009 for the EX-Z270 and 2013 for the EX-ZR800 - meaning you’ll find technology leaps, ergonomic shifts, and feature divergences that significantly impact real-world shooting. Having spent numerous hours testing cameras across various genres, I’m ready to unpack these models, highlighting strengths, potential deal breakers, and which setup suits your photographic passions best.

The Feel and Form of Two Casios: Ergonomics and Build

Size and handling often shape how a camera feels in your hands before you look at its specs. The EX-Z270 presents as an ultracompact unit - not much larger than a credit card in footprint, with a thickness reminiscent of a chunky smartphone. Its 97x55x22mm dimensions and a svelte 111g weight make it highly portable and delightful to carry in any pocket or tiny bag. This sleekness of form favors street and travel photographers who prize discretion and light carry loads.

The EX-ZR800, by contrast, is bulkier and more substantial at 108x60x31mm and 222g. It firmly sits in the compact category but sports a more robust build that feels reassuring in hand. While it won’t slip unnoticed in a jacket pocket, it remains fairly portable and benefits from a better grip surface for longer shoots, especially telephoto framing.

The physical footprints also hint at a more complex optical assembly within the EX-ZR800, supporting its expanded zoom range. Both models forego an electronic viewfinder, relying wholly on their LCDs, but design-wise, the EX-ZR800 noticeably prioritizes operational controls, which you’ll find appreciated once you start shooting in manual or semi-auto modes.

Speaking of controls: the EX-ZR800's top plate features dedicated dials and buttons, lending a hands-on feel for shutter speed, aperture, and exposure compensation - tools absent on the EX-Z270. If you prefer a simple point-and-shoot, the minimalism of the EX-Z270’s interface is appealing; for those wanting to tinker on the fly, the EX-ZR800 steps up.

Sensor and Image Quality: More Data, More Detail

The foundation of any camera’s image quality lies in its sensor technology, size, and resolution. The EX-Z270 uses a 1/2.5" CCD sensor with a 10-megapixel resolution, where each pixel captures roughly 2.47 microns of detail area. This old-school CCD, common for its time, still delivered decent images but tends to struggle with noise beyond ISO 400 when pushed.

Comparatively, the EX-ZR800 features a newer 1/2.3" CMOS sensor armed with 16 megapixels, packing a denser pixel grid but leveraged by its processor to maintain better noise control, even near ISO 1600 and beyond - an impressive feat for this sensor size. Though still compact, the sensor can suit prints up to 8x10 inches with satisfying sharpness.

One notable aspect is their zoom focal range linked to sensor size and quality. The EX-Z270 spans a modest 28-112mm equivalent (4× zoom), ideal for general snapshots and modest telephoto needs. In contrast, the EX-ZR800 pushes the envelope with an 18× zoom or 25-450mm equivalent - aspiring to capture distant wildlife, sports, or far-off landscapes.

Regarding image characteristics - expect richer dynamic range, enhanced color depth, and reduced noise from the EX-ZR800 thanks to sensor improvements paired with the EXILIM Engine HS 3 processor that manages image data with efficient algorithms. The EX-Z270's output, while respectable for casual use, lacks the subtle tonal gradations modern shooters love.

LCD Screens and User Interface: Framing and Menus that Matter

Neither model provides a viewfinder, so the reliance on the rear LCD is critical for composition and image review.

The EX-Z270 sports a 2.7-inch fixed LCD with a resolution of 115k dots. By today’s standards, this screen appears quite coarse, with limited brightness and contrast. I found it challenging to judge exposure accurately on sunny days or discern fine details for manual adjustments. It's serviceable but leaves room for guesswork.

In contrast, the EX-ZR800 elevates the experience with a 3-inch 922k-dot Super Clear TFT LCD. This means crisper live view, better color rendition, and good visibility even under strong daylight, aiding precise focus confirmation and menu navigation. For video and framing moving subjects, the more responsive screen is an undeniable advantage.

As for menus, the EX-ZR800's interface offers more depth, including customizable white balance, exposure compensation up to ±2 stops, and the ability to engage manual exposure modes. These features, not available on the EX-Z270, underscore the latter’s beginner or casual snapshot focus.

Autofocus and Shooting Speed: Catching the Moment

The difference in AF technology is stark. The EX-Z270 holds on to a simple contrast-detection AF system, only single-shot AF, no continuous tracking or face detection. In practical terms, it’s adequate for still scenes but not fast-moving subjects or complex focus scenarios. The autofocus speed is leisurely, something to note if you often shoot on the go.

The EX-ZR800, however, incorporates more modern AF features including face detection and contrast-based tracking, alongside multi-area focusing and center-weighted AF options. While not up to DSLR or mirrorless speeds, it is noticeably faster and more reliable in maintaining focus on a subject moving across the frame.

Burst shooting speed also differs: the EX-Z270 lacks burst mode, limiting you to single captures with a shutter speed cap at 1/2000s. The EX-ZR800 can burst at 3fps, modest but sufficient for casual sports or action. The shutter speed range is similar, though the EX-ZR800 allows a longer minimum shutter speed of 4 seconds - useful for creative low-light or nighttime photography.

Real-World Use: Performance Across Photography Genres

Since cameras are rarely used generically, I’ve broken down their relative strengths across common photographic disciplines.

Portrait Photography

• EX-Z270: The ultracompact form suits casual portraits and social shoots, but the modest 10MP output and limited aperture range (F2.6-7.8) restrict shallow depth-of-field rendering; bokeh is generally busy, and eye detection autofocus is absent.
• EX-ZR800: With 16MP resolution, face detection AF, and manual aperture control down to F3.5, it produces sharper eyes and smoother backgrounds at longer focal lengths. Better white balance customization also means skin tones come out more natural.
